kennyb123 Posted December 13, 2016 Share Posted December 13, 2016 Here's my first shot at this. Both my digital sources are isolated from the AC by either ultracapactiors (LPS-1 for the microRendu) or by battery+ ultracapactiors (Chord Hugo TT). No special care is taken for the devices outside my listening room including a Mac Pro (running Roon Server) and a Synology NAS (hosting my music files). Feedback welcome.

udis Posted December 14, 2016 Share Posted December 14, 2016 Great thread! Here's my topology: I am open to suggestions regarding better utilizing my JS-2. As you can see, it's driving one FMC and nothing else. I've considered bringing the sT into the listening area and powering it with the JS-2. Also, open to your thoughts on how to minimize/eliminate the Ubiquiti switch as this switch is very noisy with network activity (4 dropcams / HD Streaming / 2 nest thermostats / 4 AP). thanks.

tgb Posted December 18, 2016 Share Posted December 18, 2016 Very nice thread ! Thanks r_w ! My topology is in my signature ; hoping that it doesn't look too messy... :-) Setup is "simple" : an Optical LAN => 2 players => basic audio processing => passive bi-amplification based on 2 FDAs (Full Digital Amplifiers) => speakers 2.1 basic stuff => 2 mains are Dynaudio Core59 + sub Dynaudio 18s Actives / digital AES in / active correction on PC side Passive daddy setup is dead Link to comment
austinpop Posted December 18, 2016 Share Posted December 18, 2016 At OP's request from another thread, here is a picture of my system topology. Some context: This topology has been the subject of intense optimization with isolation tweaks on several fronts (USB, network, power). What is shown is the current optimum, but this picture will likely change over time. One thing to note specially is the position of the LPS-1 in the chain. It is counter to where many experts (and myself) thought it would fit best - which is, powering the W4 Recovery (aka RUR). Instead, the LPS-1's biggest, and most delightful impact, came when placed as shown powering the downstream FMC. I'm still scratching my head on that one, but it does underscore the point that there is no substitute to experimentation in your own system to find the optimum topology.

I'm still scratching my head on that one, but it does underscore the point that there is no substitute to experimentation in your own system to find the optimum topology. The Intona likely reduces the amount of leakage current entering via the RUR's power supply to below the amount that had been entering via the FMC's. Very interesting and exactly the right conclusion. Thanks for sharing.

Cornan Posted January 24, 2017 Share Posted January 24, 2017 Since it have happend quite a bit in my setup since my last post I will post my revised system topology as well! Revised again since I forgot to add the downhill FMCs unregulated battery pack. Cornan - revised spagetti image.pdf Link to comment

mozes Posted January 25, 2017 Share Posted January 25, 2017 My DAC don't need 5V Power. I tried to use second Vbus2 after Regen, but found it has a negative influence for SQ. My DIY grounding conditioner is a large flower pot fulfilled with 10kg od bentonite. Inside there are 5 Cooper springs, and I connect them to 6 gears. Hi Trabb Can you pls share how you connect your gear to the grounding box. Which connectors you use and what wires. Thanks Link to comment
STC Posted January 25, 2017 Share Posted January 25, 2017 Attaching my best/last Stereo setup topology and my current 12 speakers setup. I still play Stereo setup but that is mostly for demo and A/B comparisons. Edit: in the Stereo setup I was using Theta Digital DAC and not Mytek.

Trabb Posted January 25, 2017 Share Posted January 25, 2017 Hi moussaobeid ! First of all, I built grounding box by myself. I use 2,5mm thick standard copper electric wires. I personally use about 3m long wire. 2 meters of that wire I switch into a spring and put it into a jar filled with bentonite. On the other side of the wire I put a spade for example if I want to connect it to the amplifier, or I try other options depending on where I want it be connected.

Cornan Posted January 26, 2017 Share Posted January 26, 2017 Thank you for the detailed explanation. Grounding is a new topic for me and I am reading more about it before I attempt to do anything Grounding boxes are really great if you use shielded cables. It brings music to life. However, I have noticed that after removing the shields, reduced system grounding to one path and adding isolation transformer I have slowly moved my Entreq Minimus to spots with cable shields and no galvanicly isolation. Now when my setup is 100% isolated my Minimus have moved to my easy listening area. This is actually something I never though would occur. I thought it would stay for good. Bottom line: unshielded cables and galvanic isolation improves the same things as grounding boxes. I didn't realize until recently. I had great use for the grounding boxes to actually evaluate were improvements were needed and when all done it only makes things a tiny bit worse. However, I still have use for it in my secondary system and will also try to connect it to the safety ground and see if it can stay there on my primary setup.
